• ‘You don’t need the rankings to tell us where we are as a team’• Manu Tuilagi ‘looking great’ going into Ireland warm-upThe England scrum-half Ben Youngs has dismissed the significance of the world No 1 ranking after it emerged Ireland will leapfrog Wales at the summit if they win at Twickenham on Saturday.Last weekend Wales went above New Zealand to claim the No 1 spot for the first time in their history and with any win for Ireland will see Joe Schmidt’s side do the same. England could have taken top spot last weekend with a sizeable victory in Cardiff but now sit in fifth place and the highest they can go on Saturday is third. But Youngs claimed England do not use the world rankings as a gauge of their progress, even if reaching No 1 was chief among Eddie Jones’s stated aims when installed as head coach.
